Toolbox: SMT soldering tools

tookBoxLogo2.jpg

In the Make: Online Toolbox, we focus mainly on tools that fly under the radar of more conventional tool coverage: in-depth tool-making projects, strange, or specialty tools unique to a trade or craft that can be useful elsewhere, tools and techniques you may not know about, but once you do, and incorporate them into your workflow, you’ll wonder how you ever lived without them. And, in the spirit of the times, we pay close attention to tools that you can get on the cheap, make yourself, or refurbish.

I just got an evaluation unit for an Edsyn 1036 Atmoscope SMD Hot Air Work Station, for review here on MAKE. I can’t wait to try it out! I haven’t done much surface-mount and never really gathered the proper tools to do anything beyond a half-baked (pretty much literally) parts replacement. So, I was tickled by the timing of an email that came from my HacDC/Dorkbot DC compadres, Riley Porter, and MAKE contributor Alden Hart. Riley wanted to share some of what Alden had been posting to the HacDC hardware hackers e-list about SMT soldering and his toolset. This is, obviously, one person’s set-up. You might recommend other tools. Please do, in the comments.

Here are the tools I find myself always needing when doing SMT projects. Deal Extreme can be a source for many of them. Be prepared to wait a few weeks, however.

Must have:

– Those tweezers
– Soldering iron with fine pointed tip (preferably temperature-controlled)
– Soldering iron tip cleaner pad or wool
– Fine braid solder wick (the good stuff, not the cheesy surplus stuff – DX is no good here)
– 10x magnifying glass or loupe (preferably with its own light source)
– Fine-gauge solder (sorry, not at my desk to read off a dimension)
– Solder paste in a syringe with a fine nozzle
– Flux pen
– Voltmeter (VOM) with continuity tester/beeper
– Panavise or some other vise for securing board
– Dental probe for moving parts around, holding them down, and scraping things

Nice to have:

– Hot-air rework station (don’t absolutely need it, but very useful)
– Hot plate for reflow
– IR thermometer for the above
– Protective goggles to look really closely during reflow
– Digital calipers
– Solder paste in a tub
– #30 wire for fixing mistakes (wire wrap wire)
– X-acto knife or razor knife for fixing mistakes
– Extra pair of hands around to occasionally hold parts down
– Little lidded containers for little SMT parts (like these, these, and these at DX)
(DX seems to be sold out of the really nice 1″ cubes. Can’t find ’em)

  1. I’ve been doing surface mount for a number of years (14+), and I’ve had several of these. They’re basically useless.

    You’re much better off with either a Metcal with a pair of Talon tweezers (tweezers with soldering iron tips), or a proper Hakko 851-2 (or a cheap Chinese knock-off for under $100 on eBay).

    The Edsyns don’t generate enough heat with sufficient air flow to be really effective, and it takes FOREVER to get even small components (like 0603 resistors or caps) hot enough to float off.

    When I got the first one, I thought the wand had a problem, so I sent it in for service. It was returned with NPF (No Problem Found), and included the test results. The second one I had I picked up as part of a lot of other equipment. It’s sitting on a shelf gathering dust, and needs to be re-homed on eBay.

    Seriously, don’t spend your money on one of these. There are far better choices that work a LOT better.
